CEO Wendell Weeks talks about Corning Inc.’s innovations—ranging from Edison’s lightbulb to the face of your smartphone—and how its fiber-optic cables are powering the AI revolution.
Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
Ries spent the next two years under the mentorship of Littleton. Ries's interest in glass's optical properties grew, and began carving cold glass instead of blowing hot glass. Tools to sculpt large blocks of glass weren't available at the time, so Ries independently developed much of the equipment he needed during his spare time. [6]
Optical toys form a group of devices with some entertainment value combined with a scientific, optical nature. Many of these were also known as " philosophical toys " when they were developed in the 19th century.

Hakim Optical in Richmond Hill. Karim Hakimi, a native of Iran, learned to make lenses from old window glass as a child. After a stint in the navy, Hakimi worked in the optical industry in Switzerland. [1] He then migrated to Canada and opened an optical laboratory in the former Elmwood Hotel (now the Elmwood Spa) in downtown Toronto, Ontario. [2]
Additional ingredients may be added to color the glass. For example, an oxide of cobalt is used to make glass blue. [3] Broken and scrap glass, known as cullet, is often used as an ingredient to make new glass. The cullet melts faster than the other ingredients, which results in some savings in fuel cost for the furnace. Cullet typically ...
